20080218731 | Diagnostic test device - A diagnostic test device comprises means for sampling a liquid biological sample. Means is provided for reacting the sample with a reagent to provide one or more visible indicia. A photodetector for scans a detection region to produce a pulsed output indicative of the presence of the one or more indicia. The photodetector is connected to a signal processing circuit for processing the pulsed output. The signal processing circuit produces an output change in response to light intensity variation which is substantially independent of baseline current. | 09-11-2008 |
20080224719 | Diagnostic test device - A diagnostic test device comprising means for sampling a liquid biological sample, means for reacting the sample with at least one reagent to provide one or more visible indicia and an optical detector for detecting the presence of said one or more indicia, the device further comprising a releasable tether which is released by contact with the liquid sample, thereby to cause the optical detector to detect the said one or more indicia. | 09-18-2008 |
20080253931 | Diagnostic test device - A diagnostic test device comprises means for sampling a liquid biological sample and means for reacting the sample with at least one reagent to provide one or more visible indicia. The device also comprises an optical detector for detecting the presence of the one or more indicia. The device also comprises means for causing at least part of the optical detector to move over the one or more indicia. | 10-16-2008 |
